*Reminder: Check Assessment Wiki and click on the event for detail.
Assessment 1 is on 14 Sept, next Friday: This assessment is a single lesson. It is on criterion A and C, so you can expect to write in English about the mathematics.
Chapter 1 in New Trends is good revision for the math skills you will need, but remember you will need to write about the math so practice creating story problems.
Download these files and they can help you to practice writing about mathematics.
